Abstract

The present invention provides a learning device, a learning method, and a storage medium capable of ensuring a learning opportunity of a deteriorated state of a secondary battery to a certain extent. The learning device includes a learning unit (125) configured to perform charging and discharging of a secondary battery (40) that supplies electric power for running the vehicle (10) based on at least one of charging and discharging data indicating the charging and discharging of the secondary battery (40). capacity learning, and when the amount of change in the charging rate indicated by the charge and discharge data exceeds a threshold value, the capacity learning is performed; and a threshold value determining unit (123) based on the learning unit performing the The history information of the capacity learning is used to determine the threshold.

Description

technical field [0001] The invention relates to a learning device, a learning method and a storage medium. Background technique [0002] In recent years, electric vehicles utilizing electric power, and hybrid vehicles utilizing electric power and an engine are being developed. The motor mounted on the vehicle described above is driven by supplying electric power from a secondary battery such as a storage battery. The vehicle has a function of calculating the full charge capacity of the secondary battery. [0003] The full charge capacity of the secondary battery deteriorates every time charge and discharge are repeated. Therefore, there is a technique of determining the degree of deterioration of the secondary battery to suppress the deterioration of the secondary battery (for example, refer to Japanese Patent Application Laid-Open No. 2015-162991). The degree of deterioration of the secondary battery is obtained based on, for example, the integrated value of the discharg...
